Abstract

L'invention concerne des techniques adaptées pour permettre de façon flexible et dynamique la création et/ou la modification de données vocales destinées à un dispositif de détermination de position. Dans certains modes de réalisation, on présente un logiciel vocal qui comprend une base de données linguistiques et une pluralité de fichiers audio. La base de données linguistiques spécifie une syntaxe et un vocabulaire appropriés concernant des informations qui sont destinées à composer des messages sonores produits par un dispositif de détermination de position. Les fichiers sonores comprennent des mots et/ou des phrases qui peuvent être accessibles au dispositif de détermination de position de façon à communiquer les informations par l'intermédiaire d'une sortie audible. Certains modes de réalisation utilisent une trousse à outils de logiciel vocal pour construire et/ou personnaliser une ou plusieurs parties d'un logiciel vocal.
